Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Workspace Db2 for z/OS

select ... from final table ( update table for portion of business time from ... )

the problem is that an update table for portition of business time can effect more than 1 row and if this is made in a bitemporal environment the System Start is set to the first change timestamp. But you didn't know the exact time you have to read afterwards the system start time from this changed row. Because you want to avoid this to Db2 back and again to Db2 and back the only chance is to have the select ... from final table ( update table for portion of business time from ... ) which now gives a -109 SQLCode.

in our shop we have prices for every item which has this price @ time @ house scenario where this is used 100.000 times a day.

Also we have the opening times with the same scenario. This changes are not so often but it would be good also to have this solution.

In this Idea it is not the History table which has to be read its only the original table because as the syntax say from final table which is for me the original one.
